Specific Absorption Rate Analysis of Aperture Coupled Antenna for Wireless Body Area Network Applications


Objective: This work presents the design and analysis of miniaturized aperture coupled antenna. The proposed antenna is designed to operate at 2.45GHz of Industrial Scientific Medical (ISM) band and intended to use for Wireless Body Area Network Applications (WBAN). Methods/Statistical analysis: The H shaped patch with aperture coupled feeding is incorporated to get symmetrical radiation pattern. By adjusting the dimensions of ground plane notch and feed line the miniaturization and desired operating frequency is achieved. The antenna’s performance is simulated at the vicinity of human arm biological tissue model to measure Specific Absorption Rate (SAR). Findings: The proposed antenna has compact form factor of 0.32λo x 0.3λo x 0.021λo. The electromagnetic numerical simulation software shows the SAR of 2.71 W/Kg. The antenna’s performance in terms of bandwidth, gain, radiation pattern is found invariable in presence of human arm tissue model. Application/Improvements: The result shows the proposed antenna possesses low SAR and small compact form factor which can be applicable for WBAN applications
